12 classic episodes of the sci-fi adventure series, featuring Jon Pertwee as the third Doctor. Two six-part stories are included: 'Frontier in Space' (which marked Roger Delgado's final appearance in the role of The Master) and 'Planet of the Daleks', which boasts a colour-restored version of the previously-lost third episode. In 'Frontier in Space', the Doctor and Jo (Katy Manning) are caught up in the tensions between the Earth and Draconian Empires in a 26th-century interplanetary war. In 'Planet of the Daleks', the Doctor lands the Tardis on the dangerous planet Spiridon, home to a terrifying army of Daleks.
